Testo 0555 6381 6381 Differential Pressure Transmitter

0555 6381, Differential pressure transmitter with humidity/temperature option

Features with all optional accessories:

• Measurement of differential pressure, flow velocity, volume flow; optional: humidity and temperature
• Automatic zero-point adjustment guarantees high, temperature-independent accuracy and long-term stability
• Low measurement range up to 10 Pa ensures very high precision at lowest pressures
• Ethernet, relay and analog outputs allow optimum integration into individual automation systems
• The P2A software for parameterization, adjustment and analysis saves time and costs in commissioning and maintenance
• Configurable alarm management with adjustable response delay and alarm acknowledgement

The testo 6381 transmitter was specially designed for monitoring differential pressure in the 10 Pa to 1,000 hPa measuring range. In cleanroom technology, the maintenance of positive pressure prevents the entry of contaminated air. In order to keep the cleanroom conditions constant, the transmitter additionally calculates volume flow and flow velocity from the measured differential pressure. An optional probe from the testo 6610 probe series also enables simultaneous recording of humidity and temperature with one transmitter. A particularly outstanding feature of the testo 6381 pressure transmitter for differential pressure is the automatic zero-point adjustment, which ensures high accuracy and long-term stability. The integrated self-monitoring and early warning function also guarantees the operator high system availability.

Applications:

• Differential pressure monitoring between rooms; optional: simultaneous measurement of ambient temperature and humidity
• Monitoring drying processes
• Differential pressure measurement in filling processes and spray-painting systems
